git - error: RPC failed; result=22, HTTP code = 400

使用git push 项目（初始化）的时候，出现了 

error: RPC failed; result=22, HTTP code = 400

以为是gitorious 的问题。后GG得以下结果：

Workaround

• When pushing a large amount of data (initial push of a big repository, change with very big file(s)) may require a higher http.postBuffer setting on your git client (not the server). From https://www.kernel.org/pub/software/scm/git/docs/git-config.html

  http.postBuffer

  Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

原来是HTTP/1.1 做长连接POST（ Transfer-Encoding: chunked）数据的时候分片缓存大小（ http.postBuffer）的影响。修改git客户端配置如下后，问题解决

git config --global http.postBuffer 52428800

其值可以修改为更大。
